CONTAINER AND DEVICE FOR REMOVING CONTENTS FROM A CONTAINER Flled June 25 1963 United States Patent 3,262,461 CONTAINER AND DEVICE FOR REMOVING CONTENTS FROM A CONTAINER Helene Kambersky, Hegelgasse 6, Vienna I, Vienna, Austria Filed June 25, 1963, Ser. No. 290,475 Claims priority, application-Austria, Feb. 20, 1963,

Claims. (Cl. 132-79) This invention relates to a device for use with squeeze tubes, particularly for cosmetic preparations, such as masacara, lip paint or the like, in which an applicator stick guided in a resilient stripper can be inserted through an opening provided in the rigid neck portion of the tubes the stripper being accommodated in a separate sleeve member, which is provided with an internal screw thread for threaded engagement with the screw thread of the rigid neck portion of a conventional squeeze tube, which latter screw thread is provided for the closure cap.

In the known devices of this type the applicator stick has toward its free end a section formed with grooves for receiving the preparation. While this design is highly suitable for mascara, there may be applications in which such a relatively stiff applicator portion is not so suitable. Besides, the amount of preparation which can be received in the grooves is insufficient for some Purposes.

The invention provides an improved device of the kind defined hereinbefore, in which the applicator stick has a smooth, shanklike portion which has attached to its lower end a substantially cylindrical applicator element in the form of a brush, or sponge or the like, which has a core extending in the axial direction of the applicator. stick so that the excess pastelike composition is removed from the applicator when the applicator stick to pulled out of the tube through the stripper.

In this connection, the stiffening core of the applicator element is suitably smaller in diameter than the shank of the applicator stick and the outside diameter of the applicator element exceeds that of the shank.

The applicator element may be replaceably secured to the end of the shank by a screw-threaded connection between the core of the element and the shank.

The invention will be described more in detail with reference to illustrative embodiments shown on the drawing, wherein:

FIG. 1 is a view showing atube provided with a device according to the invention, partly in section, and FIGS. 2 and 3 show second and third embodiments of the applicator stick.

A sleeve member 4 is screw-threaded on the external screw thread 1 of the neck portion 2 of a squeeze tube 3. The bore of the sleeve member 5 is offset to form a bearing shoulder 5. A resilient stripper 6 is clamped between this bearing shoulder and the top end of the threaded neck 2 and is formed with a central opening 7. A cap 8 is mounted on the sleeve member 4 and in its lower portion has seat faces 9 conforming to the outside contour of the sleeve member. An applicator stick 10 is secured in the cap 8 and extends through the opening 7 of the stripper 6 into the preparation 11 contained in the tube 3. The applicator stick 10 has a smooth, cylindrical portion 12, which is secured to the cap 8 and forms a shank for an applicator element, such as a brush 13, which is attached to the lower end of the shank. The applicator 3,262,461 Patented July 26, 1966 "ice element has a core 14, which extends in the axial direction of the applicator stick and is integral with and smaller in diameter than the shank 12. The applicator element consists preferably of a brush 13 for receiving the preparation contained in the tube. The bristles 15 of the brush 13 are attached to the core. Alternatively, the applicator element may consist of a spongelike body 16 (FIG. 3) surrounding the core 14, or of a compressible pad.

The latter may comprise a layer of wadding surround- I ing the core 14 and covered with a wrapper consisting of a woven fabric. The outside diameter of the applicator element 13, 15 exceeds that of the shank 12, so that the withdrawal of the applicator stick 10 from the tube 3 will cause the stripper 6 to remove the superfluous-pastelike composition firom the applicator element. Because the stripper engages the shank 12 of the applicator stick, the latter will remove portions of the contents 11 of the tube only with the applicator element and only in the amount required for the respective purposes. This amount of contents of the tube to be carried by the applicator element 13, 15 after its withdrawal from the tube may be predetermined by an appropriateselection of the outside diameter of the applicator element and its core 14 in relation to the outside diameter of the shank 12.

In some cases it may be desirable to enable a replacement of the applicator element. For this purpose, the applicator stick 10 may be detachably secured to the cap 8 or, as is apparent from FIGS. 2 and 3, the applicator elements 13, 15 may be detachably mounted to the lower end of the shank 12 of the applicator stick 10. The latter mounting is preferably effected by a screw-threaded joint 17 between the core 14 and the shank 12.

What is claimed is:

1. A cosmetic dispenser device adapted to receive a paste-like prep-aration, comprising a collapsible tube including a screw threaded neck having an upper rim, a sleeve member with a central bore having two portions of different inner diameters forming an inner shoulder, the larger portion being threaded and screwed onto the screw threaded neck of the tube, a disc-shaped stripper member inserted in said larger portion of the sleeve member and sandwiched in abutting relation against said inner shoulder in said sleeve member and the rim of the neck, said stripper member having a central bore, a removable cap in slidable engagement with the outer surface of said sleeve, said cap having secured thereon an applicator rod in gripping engagement with said central bore of the disc-shaped stripper member, the applicator rod including an end portion provided with interstices for receiving the contents of said tube, said tube being sufficiently collapsible to squeeze its contents in the proximity of said end portion.

2. A device as claimed in claim 1 wherein said end portion has an outer diameter greater than .thatof the remainder of the applicator rod.

3. A device as claimed in claim 1 wherein said rod includes a cylindrical shank portion, said end portion comprising a core having a smaller diameter than said shank portion and bristles on said core defining an outer diameter exceeding the diameter of the shank portion.

4. A device as claimed in claim 3 comprising means detachably securing the core and shank portion together.

5. A device as claimed in claim 1 wherein said end portion comprises a body of absorbent material, said body having an outer diameter exceeding the diameter of the remainder of the applicator rod and related to the diameter of the opening in the stripper to provide a prescribed 3 4 quantity mate-rial on said body when the latter is removed 2,902,041 8/1959 Bau 13279 from the tube. 3,071,143 1/1963 Bau 13288.7 3,073,320 '1/1963 Scavcr l3Z-79 References Cited by the Examiner UNITED STATES PATENTS 5 RAPHAEL M.
